The social mentality for doctor-patient relationship refers to the dominant cognition, emotion, attitude, and values concerning doctor-patient relationship which are shared by the majority of a particular society. It consists of three levels: the interpersonal level, the inter-group level, and the cultural level. Studies on the formation mechanism of the social mentality for doctor-patient relationship should focus on how the interpersonal cognition, emotion, and belief gradually evolve into an inter-group mentality and then into a cultural mentality and how the cultural mentality influences the inter-group mentality and the interpersonal mentality. The strategies for constructing a healthy doctor-patient social mentality are threefold. Firstly, at the interpersonal level, medical workers should master communication skills and strategies. Secondly, at the inter-group level, the interaction pattern between the patient group and the doctor group should be modified and the community of doctors and patients should be constructed. Thirdly, at the cultural level, the medical philosophy, the medical discourses, the media image of doctor-patient relationship, and the current medical education system should be improved and updated.
